The Steca range of regulators are, in my opinion, the best, with the PR 2020 giving you all the info you need. However once one has done the checks a few times it gets quite boring and the price seems more than you need to have paid. I run all the lighting and recharge my cordless tools from 4 x 50 watt panels, PR 2020 regulator and 2 x 105 amp deep cycle batteries. I hardly bother looking at the regulator any more.
The PRS range is excellent, without the LCD display, and you will not need a bigger one than the 1010 (10 amp/hr) given that your panel is 80 watt. This produces a maximum current of about 4.7 amps and therefore a 10 amp regulator is fine. The bottom of the Steca range is the Solsum F and this is also available in 6, 8 and 10 amps. They also are excellent.
Hope this is of use. I supply OW with another range of folding panels and specify them with PRS regulators, having recently changed from TES.
